Review on Advanced GPS Multisport Watch with Wrist-based Heart Rate - Polar Vantage M (Lightweight Design & Latest Technology) by Rodney Harris

Overall I really like this heart rate monitor, the only downside is that it doesn't measure my heart rate correctly 100% of the time. I bought it to replace a very very very old Garmin. I think it's "fun" to be able to wear it 24 hours a day, 7 days a week and track your activity + sleep, but that's not what I bought it for. I just had to keep track of my training and heart rate. Some positive points: I think it's a nice watch. The interface is easy to use and I love all the sport profiles available. My favorite thing so far has been that I could buy it small. I have very small wrists and being able to get it snug enough around my wrist without a long ponytail is a luxury. Cons: My only downside is that it doesn't track my heart rate correctly for all sports. It is ideal for strength training, Pilates and indoor cycling. But when I wear it to run or use the elliptical trainer, it's completely inaccurate. Based on reading another review I think it has trouble reading correctly when I have a lot of hand movement. So I will buy a heart rate strap during these sessions. Admittedly, it would be handy if the heart rate measurement via my wrist worked 100%. But I was skeptical from the start, so I'm not shocked by the problems.
